Fixed prosthodontics
Summary
Fixed prosthodontics is the branch of prosthodontics that focuses on dental prosthesis that are permanently affixed (fixed). Crowns, bridges (fixed dentures), inlays, onlays, and veneers are some examples of indirect dental restorations. Prosthodontists are dentists who have completed training in this specialty that has been recognized by academic institutes. Fixed prosthodontics can be used to reconstruct single or many teeth, spanning tooth loss areas. The main advantages of fixed prosthodontics over direct restorations are improved strength in big restorations and the possibility to build an aesthetic-looking tooth. The concepts utilised to select the suitable repair, as with any dental restoration, include consideration of the materials to be used, the level of tooth destruction, the orientation and placement of the tooth, and the condition of neighboring teeth

A large amount of tooth structure is removed irreversibly during crown preparation. All restorations have impaired structural and functional integrity when compared to healthy, natural tooth structure. As a result, if a dental practitioner does not recommend it, crowning a tooth is probably not a good idea. Dentists trained at different institutions in different times and countries may have varied ways of treatment planning and case selection, resulting in varying treatment recommendations.
Traditionally, crown and bridge work requires more than one visit, and the extra time necessary for the procedure can be a drawback; nevertheless, the improved benefits of such ainvolvetion will generally outweigh these factors.
When preparing a tooth for a crown, the preparation should, ideally, exist entirely in the enamel. As elaborated on below, the amount of tooth structure required to be removed will depend on the material(s) being used to restore the tooth. If the tooth is to be restored with a full gold crown, the restoration need only be .
